How could a building like the Mishkan or the Beit HaMikdash, or a natural phenomenom like a cloud (at Har Sinai) contain the Presence of the Almighty (Ubiquitious, the infinite volume; omnipotent; omnipresent; omniscient etc. G-d)?

@DoubleAA 1 Kings 8:12-13; Schneerson: “With the commandment to erect a Sanctuary, G-d gave the promise ‘I will dwell within’. That promise was fulfilled with the manifestation of G-ds Presence in the Sanctuary. The Divine Presence within our material world. [I.e. His immanent presence, rather than יהוה Himself].
